- 20 mm x 1.5 thread specification as listed for the 18-7913 application.
- Anti-drainback valve helps reduce oil drain-back during engine shutdown and supports oil circulation during the next start.

- Apply a thin film of clean engine oil to the new filter gasket.
- Thread the new filter onto the mounting point by hand until the gasket contacts the sealing surface.
- Tighten the filter by hand according to the engine manufacturer's service instructions. Do not overtighten or use excessive wrench force.
- Refill the engine with the manufacturer-specified oil and check the level.
- Start the engine briefly, inspect the filter area for leaks, shut the engine off, and recheck the oil level after the oil settles.
Always follow the engine manufacturer's service manual for oil type, oil quantity, tightening instructions, and maintenance intervals.
Troubleshooting & FAQ
How do I confirm that this filter fits my engine?
Compare the part number on your existing filter or in the engine service manual with the references listed on this page. Confirm the complete engine model, year, serial-number range, and stroke designation where applicable. Do not use horsepower alone to determine fitment.
Is this an OEM filter?
No. This is an aftermarket replacement filter. Mercury Mariner and Honda part numbers are shown only as replacement and identification references.
Can I use this filter on a two-stroke engine?
No. This filter is intended for compatible four-stroke outboard applications. Confirm the required filter reference before installation.
What does the anti-drainback valve do?
The anti-drainback valve helps limit oil draining back into the crankcase while the engine is stopped, which can support faster oil availability during the next start.
What should I do if the filter leaks after installation?
Stop the engine immediately. Check that the old gasket was removed, the new gasket is seated correctly, the filter is installed straight, and the filter is tightened according to the manufacturer's instructions. Do not continue operating the engine with an oil leak.
How often should the oil filter be replaced?
Replace the filter at the interval specified in your engine manufacturer's maintenance schedule, normally during an oil change. Service intervals vary by engine model and operating conditions.
Safety & Important Information
- Verify the original part number, thread specification, and application before ordering.
- Do not install this filter on an engine requiring a different filter reference or thread size.
- Dispose of used oil and the old filter in accordance with local regulations.
- Professional installation is recommended if you are not familiar with marine engine servicing.
